Ocean Wave Directional Spectra by Optical Methods
Ocean wave directional spectrum studies are basic and crucial in the study of ocean waves, and play an important bearing in both theory and application of wave researches (Wen and Yu, 1985). Researches in ocean wave directional spectra depend closely on the survey techniques for waves, which include direct in-situ measuring and remote sensing. In direct measuring with free-floating buoy and sensor staff array, instruments operate either in direct contact with ocean wave or very close to it, this brings about many handicaps and limitations. In the contrary, remote sensing is of incomparable superiority in measuring ocean wave directional spectra.
